“It goes without saying they were a threat to our elections in 1974, they interfered in our elections in the '80s,” Pompeo said during an event at the Council on Foreign Relations hosted by The Hill’s Newsmaker Series.

“The fact that this town seemed shocked by the fact the Russians don’t care for us — in that case the Soviet Union — I find stunning,” Pompeo said, adding that books have recounted the Russian threat “over an extended period of time.”

“We should expect in 2050 the Russians will still be at it still,” Pompeo said at the event, which was sponsored by the Partnership for Open and Fair Skies.

“We should all be cognizant about the sources of the information we receive. We should be cognizant when we receive dossiers to make sure that they are right, that we have validated information before we report on it,” Pompeo said, apparently making a passing reference to the so-called Steele dossier containing salacious and unverified allegations about Trump’s ties to Moscow.

Pompeo described the threat as much broader than Russia — coming from China, Iran and non-state actors whose cyber capabilities could impede not only U.S. elections but also the functioning of the nation's infrastructure, including the financial system and telecommunications.

Pompeo said the Obama administration should have done more to prevent Russia’s interference and that the Trump administration has taken steps to make sure it doesn’t happen again.

“We have the mission now to make sure this doesn’t happen,” Pompeo said.

Over the course of his 22-month investigation, Mueller charged more than two-dozen Russians for the interference effort, which Moscow has systematically denied despite the U.S. intelligence community’s conclusions. Trump has seemed to begrudgingly accept the finding that Russia meddled in the election to tip the scales in his favor.

Trump regularly attacked Mueller’s probe as a “witch hunt” and has embraced its finding of no conspiracy between the campaign and Moscow. Mueller did not reach a conclusion on whether the president obstructed the probe.
